In another thread OHbowhntr turned me onto OnTarget2 and I was wondering about its accuracy and/or if there were better ones.
Good question Phillip. I also await the answer to this. I am geeky like that to want to play with calculation programs.
OT2 and Archer's Advantage are the two I am familair with. I prefer OT2 but it takes a bit more working with and learning to get it to perform at its best. AA is easy to use and gives you good, solid feedback with a minimal learning curve.
http://www.pinwheelsoftware.com/ - This is OnTarget2 http://archersadvantage.com/ - Archer's Advantage One other thing. AA prints awesome targets. I print targets on regular paper all the time and tape them to my bags. Great for shooting at long range. OT2's targets suck. Other than that I use OT2 the most.
I have been using the OT2 software for several years now and found it pretty accurate. I dont believe it covers bows earlier than 2002 though. I have not tried AA yet.
